Vehicle control device

Abstract

When a state in which fuel supply to a combustion chamber of an internal combustion engine is cut is recovered, since a vehicle control device starts the fuel supply by controlling the internal combustion engine at the time that a requested driving force that is being requested becomes the same as an actual driving force that is being actually generated, the vehicle control device can appropriately start the fuel supply when the fuel cut state is recovered. When, for example, the deviation between the requested driving force and the actual driving force becomes within a preset and predetermined range, as the time at which the requested driving force that is being requested becomes the same as the actual driving force that is being actually generated, the vehicle control device starts the fuel supply.

The invention claimed is: 
     
       1. A control device for a vehicle, the vehicle having an internal combustion engine, and a combustion chamber provided in the internal combustion engine, the combustion chamber being supplied with air and fuel, the control device comprising:
 an electronic control unit programmed to start fuel supply, the electronic control unit being programmed to start the fuel supply when a state, in which the fuel supply to the combustion chamber of the internal combustion engine is cut, is recovered, by controlling the internal combustion engine at a time a requested driving force being requested becomes the same as an intake pipe pressure estimated driving force, the intake pipe pressure estimated driving force being: (i) estimated from an intake pipe pressure of the internal combustion engine, and (ii) generated at a time of recovery from the fuel cut. 
 
     
     
       2. The control device for a vehicle according to  claim 1 , wherein the electronic control unit is programmed to start the fuel supply at a time that a deviation between the requested driving force and the intake pipe pressure estimated driving force becomes within a predetermined range. 
     
     
       3. The control device for a vehicle according to  claim 1 , wherein, in the state in which the fuel supply is cut, the electronic control unit is programmed to increase an opening degree of an intake path to the combustion chamber as compared with a state in which the fuel supply is not cut. 
     
     
       4. The control device for a vehicle according to  claim 2 , wherein, in the state in which the fuel supply is cut, the electronic control unit is programmed to increase an opening degree of an intake path to the combustion chamber as compared with a state in which the fuel supply is not cut.
